体= 'CMD =' + urllib_parse.quote_plus（UNICODE（动词）.encode（ 'UTF-8'））返回 “名称 '的unicode' 没有定义”

Question

当我关于Python 3.4

运行下面的Python代码

# -*- coding: utf-8 -*- 
import unittest, time, re 
from selenium.selenium import selenium 

class google(unittest.TestCase): 
    def setUp(self): 
     self.verificationErrors = [] 
     self.selenium = selenium("localhost", 4444, "*chrome", "https://www.google.com/") 
     self.selenium.start() 

    def test_google(self): 
     sel = self.selenium 
     sel.open("/?gws_rd=ssl") 
     sel.type("id=gbqfq", "") 
     sel.type("id=gbqfq", "test") 

    def tearDown(self): 
     self.selenium.stop() 
     self.assertEqual([], self.verificationErrors) 

if __name__ == "__main__": 
    unittest.main() 

我有错误name 'unicode' is not defined:

====================================================================== 
ERROR: test_google (__main__.google)

    File "google.py", line 11, in setUp

    body = 'cmd=' + urllib_parse.quote_plus(unicode(verb).encode('utf-8')) 
NameError: name 'unicode' is not defined

有什么不对？有没有办法解决它？

Answer 1

就像它说的那样，unicode不再是3.x中的内置 - 而是str类型描述了一个Unicode字符串。

您不应该收到此消息，因为它发生在Selenium代码中。这表明你已经安装了不当的Selenium - 你有2.x代码，但是试图从3.x中使用它。

对文档的快速检查表明Selenium支持3.x - 但您需要卸载并重新安装它，并确保此时能正确安装。
